A whip antenna is an antenna consisting of a single straight flexible wire or rod, often mounted above some type of conducting surface called a ground plane. The bottom end of the whip is connected to the radio receiver or transmitter. They are designed to be flexible so that they won't break off, and the name is derived from their whip-like motion when disturbed. Often whip antennas for portable radios are made of a series of interlocking telescoping metal tubes, so they can be retracted when not in use. They are the most common type of monopole antenna. These antennas are widely used for hand-held radios such as cell phones, cordless phones, walkie-talkies, FM radios, boom boxes, Wifi enabled devices, and GPS receivers, and also attached to vehicles as the antennas for car radios and two way radios for police, fire and aircraft.

Famous quotes containing the word whip:
“... my mother ... piled up her hair and went out to teach in a one-room school, mountain children little and big alike. The first day, some fathers came along to see if she could whip their children, some who were older than she. She told the children that she did intend to whip them if they became unruly and refused to learn, and invited the fathers to stay if they liked and she’d be able to whip them too. Having been thus tried out, she was a great success with them after that.”
—Eudora Welty (b. 1909)
